Seat Formentor Engine Issue

I'm reaching out in desperation regarding my 2022 Seat Formentor with a gasoline engine. The dreaded check engine light has illuminated, and I'm experiencing significantly reduced engine power, poor engine response, and what seems like higher fuel consumption. My OBD scanner is showing a fault related to the crankshaft to camshaft reference value. The car has 185969 km on the clock. Any thoughts on where to start?

A 2022 Seat Formentor owner experienced a check engine light, reduced engine power, poor response, and increased fuel consumption. The OBD scanner indicated a fault related to the crankshaft to camshaft reference value, specifically error code P0335, pointing to the crankshaft position sensor. The suggested solutions included checking the sensor and its wiring harness for damage and considering a potential timing chain issue. Ultimately, replacing the defective crankshaft sensor resolved the problem, restoring the vehicle's performance.

Did this summary help you solve your problem?

Whoa, that sounds rough. Crankshaft to camshaft reference value – are you seeing any specific error codes? Did this happen suddenly, or did you notice performance degrading over time? Could be a timing chain issue too if it's jumped a tooth, though the sensor is definitely the first place to look.

Thanks for the quick reply. The error code I pulled was P0335, which points to the crankshaft position sensor. If the timing chain skipped a tooth, wouldn't I expect to see other related codes or hear some unusual noises? What exactly should I be looking for to rule out the timing chain?

P0335 definitely screams crankshaft sensor. If the timing chain jumped, you'd likely get misfire codes too. Still, at that mileage, a stretched timing chain isn't out of the question, especially if oil changes weren't always on time. Check the sensor wiring harness for damage first. Honestly, though, with those symptoms, I'd get it to a workshop and have them scope it out. Best not to risk further damage.

The defective crankshaft sensor was indeed the problem. Replaced it at a cost of 340€. Runs like new. Thanks for your insight, I really appreciate it.
